What does 'file-fit' mean for these piston rings?

File-fit means the ends of the piston rings are not pre-gapped. You will need to carefully file them down to the correct gap for your specific cylinder bore size during installation. This allows for a more precise fit and better sealing.

What is the purpose of the different ring types?

The top ring seals combustion pressure, the second ring helps control blow-by and also aids in sealing, and the oil ring scrapes excess oil from the cylinder walls to prevent it from entering the combustion chamber.

Are these rings suitable for high-performance engines?

Yes, JE Pistons is a popular brand for performance engine builds. The plasma moly top ring and iron phosphate second ring are designed for good sealing and durability, which are important for performance applications.
